New terms needed

[cmungall]

We will need some new envo terms:

name: ephemeral island def: An island, usually the consequence of the activity of a submarine volcano, that only exists for a short period or short periods of time after its formation, then being eroded or otherwise disappearing beneath the surface of a body of water. definition reference: MA:ma as a isa of island

name: tuya def: A distinctive, flat-topped, steep-sided volcano formed when lava erupts through a thick glacier or ice sheet. definition reference: http://en.wikipedia.org/wiki/Tuya isa volcano

name: complex volcano def: A volcano with more than one feature. They form because changes of their eruptive characteristics or the location of multiple vents in an area. Stratovolcanoes may form complex volcanoes, because they may overlap another from explosive eruptions, lava flows, pyroclastic flows and by repeated eruptions, to make multiple summits and vents. Stratovolcanoes could also form a large caldera that gets filled in by multiple small cinder cones, lava domes and craters may also develop on the caldera's rim. exact synonym: compound volcano definition reference: http://en.wikipedia.org/wiki/Complex\_volcano isa volcano

name: pyroclastic shield volcano def: A shield volcano that isformed mostly of pyroclastic and highly explosive eruptions rather than relatively fluid basaltic lava issuing from vents or fissures on the surface of the volcano. They typically display low-angle flank slopes and have little or no central collapse, although a shallow sag in the shield is commonly observed. Lava is commonly extruded after the cessation of explosive activity commonly superposes the vent region. definition reference: http://en.wikipedia.org/wiki/Pyroclastic\_shield exact synonym: terrestrial ignimbrite shield isa shield volcano

name: geothermal field def: An area where wells can be drilled to obtain elements contained in solution in hot brines or to tap heat energy. definition reference: http://www.webref.org/geology/g/geothermal\_field.htm isa volcanic feature

On the matter of "volcano" there are clearly very different ecological consequences of a Devonian volcano and one that is now active. Both are "volcanoes". So I suggest, for discussion at least

Pleistocene volcano Holocene volcano Pre-pleistocene volcano [these are dead as a dodo as far as I know, we may well, sometime, want to split this into "Cretaceous volcano" "Cambrian volcano" but I see no reason do this now.]

I think that "submarine volcano" can be merged into "seamount", they seem to be used synonymously. Also please delete the word : "extinct" from the def of seamount. It should also be moveed to be a child of "volcanic hydrographic feature:

New children of "protected area"

name: Wildlife Management Area def: A protected area with the purpose of protecting and managing wild life. definition reference: MA:ma

"national wildlife refuge" should be a child of this term

name: World Heritage Site def: a specific site (such as a forest, mountain, lake, desert, monument, building, complex, or city) that has been nominated and confirmed for inclusion on the list maintained by the international World Heritage Programme administered by the UNESCO World Heritage Committee. definition reference: http://en.wikipedia.org/wiki/World\_heritage\_site

name: Biosphere Reserve def: an international conservation designation given by UNESCO under its Programme on Man and the Biosphere (MAB). definition reference: http://en.wikipedia.org/wiki/Biosphere\_reserve

Added terms and made suggested changes to the ontology.

Still open for discussion: On the matter of "volcano" there are clearly very different ecological consequences of a Devonian volcano and one that is now active. Both are "volcanoes". So I suggest, for discussion at least
